4 Lewisville Independent School District August 17, 2015 Apex Project No Page SCOPE OF SERVICES Apex TITAN, Inc., a subsidiary of Apex Companies, LLC (Apex) was engaged by Lewisville Independent School District to conduct a post-remediation mold assessment and clearance sampling for the remediation area at Marcus High School ROTC Hallway located at 5707 Morriss Road, in Flower Mound, Texas ( Site ). Apex's Post-Remediation Assessment and Clearance Services (hereinafter the Services ) were conducted for the Remediation Area of the site in accordance with the scope of work set forth in Apex s Proposal P dated June 24, Apex s services for this project included: Visual Reconnaissance of the Lewisville Independent School District identified mold remediation areas (as defined in Section 3.2 below) to verify that the Remediation Area is free from all visible mold and wood rot. Visual reconnaissance of the Remediation Areas and review of the project Mold Remediation Protocol and Remediation Work Plan for the project to verify that the mold remediation work was completed in compliance with the Remediation Protocol and Work Plan. Conduct verification sampling in Remediation Areas and compare results to clearance criteria in project Mold Remediation Protocol. Determine, based upon available information, whether the moisture source identified as the underlying cause of the mold in the Remediation Areas was properly remediated such that it is reasonably certain that the mold will not return from that remediated cause. If clearance criteria for the Remediation Area(s) have been achieved, prepare the Mold Assessor s portion of the Mold Remediation Certificate (on Texas Department of Insurance Form MDR-1). 2.0 STANDARD OF CARE, RELIANCE AND LIMITATIONS 2.1 Standard of Care Apex performed the Services in accordance with generally accepted practices of the profession undertaken in similar services at the same time and in the same geographical area. No other warranties, express or implied, apply to the Services hereunder or this report. 2.2 Reliance The Services were conducted and this report prepared for the benefit and exclusive use of the CLIENT and solely for its use and reliance in assessing whether mold in the project Remediation Areas of the Site had been remediated within clearance criteria set forth in the Mold Remediation Protocol. The CLIENT was the only party to which Apex explained the risks and limitations of the Services and was solely involved in shaping the scope of services. Accordingly, reliance on this report by any other party may involve assumptions leading to an unintended interpretation of findings and opinions. With the consent of the CLIENT, Apex may offer reliance to third parties or contract with other parties to develop findings and opinions

5 Lewisville Independent School District August 17, 2015 Apex Project No Page 2 related to such party s unique risk management concerns. Notwithstanding the foregoing, reliance by any and all third parties upon the Services or this report shall be limited in the aggregate to the fair market value of the Services. 2.3 Definitions Mold defined. Mold is a general term used to describe various types of naturally occurring biological organisms occurring worldwide. For purposes of this report (and regulations), the term mold is broadly defined to include any living or dead fungi or related products or parts, including spores, hyphae, and mycotoxins. Remediation Area means that portion of the Site where mold remediation activities have been completed and as more particularly defined in Section 3.2 of this report. 2.4 Services and Report Limitations Time sensitive. One must keep in mind that mold assessments, including post-remediation mold assessment and clearance sampling, are essentially a snap-shot in time, and the results are only relevant as of the time of site reconnaissance and sampling. Because mold, when biologically active, is a living organism, its presence is influenced and controlled by environmental conditions. Mold assessments, therefore, are time sensitive in that the presence and concentration of mold and similar organisms in building structures or in the air is directly influenced by environmental conditions (such as humidity, moisture, nutrients and substrates), whether natural or caused by man, which conditions may vary significantly over relatively short periods of time. Methodologies. Currently, mold assessment methodologies and protocols in Texas are governed by persuasive guidelines (rather than promulgated federal/state or local regulations). Presently, there is no data that supports a threshold limit or dose-response relationship for exposure to mold aeroallergens, individual pathogens, opportunistic pathogens and/or mycotoxins. The Occupational Safety and Health Administration (OSHA), the National Institute of Occupational Safety and Health (NIOSH) and other non-governmental associations, have not yet established permissible exposure limits (PELs), recommended exposure limits (RELs), or other limit values for aeroallergens. Because no limit values presently exist, Apex will not and cannot represent that the site contains no harmful microbes, mold, fungi, or their metabolites, or other latent conditions beyond those identified by the limited scope of this mold assessment. Moisture Intrusion Limitation. Apex is not a moisture intrusion, HVAC, plumbing, roofing or building envelope contractor or specialist ( Building Trades Specialist ). In performing the Services, Apex has relied upon statements, certifications and/or findings made by the CLIENT, Site owner or Building Trades Specialists that the moisture source which is the underlying cause of mold in the Remediation Areas has been identified and remediated such that it is reasonably certain that the mold will not return from that remediated cause. Findings Limited. Apex s findings from the Services are limited due to their time-sensitive nature and because they rely in part upon information prepared or provided by the CLIENT, the Site owner or third parties. Apex cannot warrant the accuracy of any services, investigations, information, data, reports, findings or conclusions prepared, made or performed by any other party in connection with the Mold Remediation Areas or other activities at the Site. Apex assumes no responsibility or liability for errors in information or data provided by or through the CLIENT, the Site owner or any third party sources. Apex s services are not to be construed as legal or medical interpretation or advice.

6 Lewisville Independent School District August 17, 2015 Apex Project No Page 3 Mold Remediation Certificate. For mold remediation projects (above certain size thresholds), applicable Texas law (i.e., Texas Occupation Code Section and T.A.C. Section (the Texas Mold Assessment and Remediation Rules), requires that a Certificate of Mold Remediation (hereinafter, Mold Remediation Certificate ) be issued by the Mold Remediation Contractor upon successful completion of the project. This certificate must be provided to property owners no later than the 10 th day after the date on which the mold remediation is completed at a property. The Mold Remediation Certificate issued by the Mold Remediation Contractor must include a certification by the Mold Assessor that the mold remediation project has been successfully completed in accordance with the mold remediation protocol. Be advised that Apex s issuance of a Mold Remediation Certificate upon successful completion of a Mold Remediation project does not mean, warrant or otherwise guarantee that mold will not be subsequently found in any portion of the Remediation Area or the Site. 3.0 SITE DESCRIPTION AND REMEDIATION AREAS 3.1 Site Description Based on the information provided by the client, the site consists of fungal growth associated with sheetrock ceiling within the shower area of the men s baseball locker room/shower area at Hebron High School. 3.2 Remediation Areas Mr. Paul Siddall of Lewisville Independent School District has identified the following physical portions of the Site as the Remediation Areas for performance of the Services: ROTC Hallway at Marcus High School. The Site diagram in Appendix A depicts the Remediation Area of the Site. Apex s Post Remediation Mold Assessment and Clearance Services will be limited to the Remediation Area. Additional areas or portions of the Site are out-of-scope and not covered by the Services or this report. 4.0 MOLD ASSESSMENT AND MOLD ANALYTICAL RESULTS 4.1 Post-Remediation Mold Assessment Results Apex conducted a post-remediation mold assessment on July 2, 2015 which did achieve the analytical clearance criteria. Apex s reconnaissance of Remediation Areas revealed that remediation containment structures were in place and air filtration was observed to be operating. Apex's visual reconnaissance showed the Remediation Areas, to be free of all visible mold and wood rot. Photographs documenting the condition of the Remediation Areas are contained in Appendix B. In conjunction with its visual reconnaissance of the Remediation Areas, Apex reviewed the Mold Remediation Protocol and Mold Remediation Work Plan for the Remediation Areas. Apex s visual reconnaissance of the Remediation Areas indicated that the Mold Remediation Contractor conducted the mold remediation activities in general accordance with the Mold Remediation Protocol and the Mold Remediation Work Plan for the Remediation Areas. Copies of the Mold Remediation Protocol and the Mold Remediation Work Plan are contained in Appendix C and D, respectively.

7 Lewisville Independent School District August 17, 2015 Apex Project No Page Mold Analytical Results The abatement was performed within one containment. Apex collected two samples inside the containments and two exterior samples utilizing Air O Cell cassettes. Air O Cell refers to slit impaction air sampling cassette manufactured by Zefon. The collection media for these devices consist of a coverslip coated with a sticky transparent acrylic substrate. Containment clearance is contingent upon passing a visual and procedural inspection by an Apex representative in addition to obtaining air monitoring results indicating that airborne mold spore concentrations inside the containment are no more than 40% of those obtained outside the structure at the time the sampling was performed. In addition, non-target airborne mold spore concentrations must be similar inside the containment than those obtained outside the structure at the time the sampling was performed. Target molds should be individually less than or equal to outside levels. However, no levels of Stachybotrys will be accepted. The target list of molds would generally include, but are not limited to, Aspergillus, Penicillium, Aureobasidium, Chaetomium, Fusarium, Trichoderma, Stachybotrys, and Ulocadium. Upon collection, samples were identified and a chain-of custody-form was prepared. Two clearance testing sampling events were performed on separate dates within the containment area. The samples were submitted to Steve Moody Micro Services, LLC (SMMS) for subsequent analysis. SMMS is licensed by the State of Texas and maintains in-house quality control/quality assurance programs for their laboratory services. Total fungal spore concentrations within the containments that achieved clearance on July 2, 2015 ranged from 754 to 1,648 counts/m 3 while the exterior levels ranged from 19,969 to 20,131 counts/m 3. Analytical reports are contained in Appendix E. Laboratory analytical results for the samples confirm that the mold clearance criteria set forth in the Mold Remediation protocol were successfully achieved. 4.3 Underlying Cause of Mold Based upon the documentation provided to Apex (copy attached in Appendix F), the source of moisture was identified as: moisture coming through the outside wall from the roof coping. Based upon the documentation provided by Mr. Paul Siddall of Lewisville Independent School District, the underlying source of moisture causing mold in the Remediation Areas was successfully remediated. A copy of this documentation is contained in Appendix F. 5.0 FINDINGS Apex s findings are as follows: Based upon Apex s visual reconnaissance of the Remediation Areas on July 2, 2015 the Remediation Area is free from all visible mold and wood rot. Based upon Apex s visual reconnaissance of the Remediation Areas and review of the Remediation Protocol for the project, the remediation work was completed in compliance with the Remediation Protocol.

8 Lewisville Independent School District August 17, 2015 Apex Project No Page 5 Based upon Apex s visual reconnaissance of the Remediation Areas and review of the Remediation Work Plan for the project, the remediation work was completed in compliance with the Remediation Work Plan. Based upon the moisture intrusion report prepared by Mr. Paul Siddall, the moisture source identified as the underlying cause of the mold was moisture due to moisture coming through the outside wall form the roof coping. Based the information provided to Apex by Mr. Paul Siddall, the source has been properly remediated such that it is reasonably certain that the mold will not return from that remediated cause. Temperature and relatively humidity readings were taken during the post remediation inspection on July 2, Temperature readings were reported as 80.7 degrees Fahrenheit inside the containment while relative humidity was reported as 65.3 percent. Temperature readings taken outside the building ranged from 84.7 to 87.6 degrees Fahrenheit while relative humidity ranged from 44.7 to 45.1 percent. Based upon Apex s visual reconnaissance of the Remediation Area(s) and its clearance sampling analytical results, the remediation activities were successfully completed by the Remediation Contractor and meet the clearance criteria specified in the Remediation Protocol. A copy of Apex s Mold Assessor) portion of the Mold Remediation Certificate (on Texas Department of Insurance Form MDR-1) in contained in Appendix F. 6.0 CONCLUSIONS The mold remediation activities in the Remediation Area has been successfully completed, passed clearance, and the Remediation Areas approved for reconstruction.
